My father is an alcoholic and it has affected our relationship a lot. I've heard stories from my mother about how he was when I was younger and he seems to have mellowed out a lot over the years and is no longer an angry drunk, but he's still hard to deal with when he's been drinking. Short phone calls turn into him rambling for hours on end. He doesn't take care of himself or his home so he never wants people to come over and most of the time he'd rather drink than go out with us for anything. I dragged him out for father's day to try and spend some time with him and he was reluctant to go, giving me numerous opportunities to back out "without guilt" but I still went and took him out to lunch anyway. He keeps saying he's going to quit drinking, and he'll stop for a few days, but then he's right back at it again. I've encouraged him to go to AA, I have friends that have done it and would have no problem helping him as much as they could, but I also know that you can't help somebody who doesn't want help so until he makes the decision to go to AA or take some other step I don't really see anything changing.
I can handle him being rather antisocial when he's drinking, I'm a bit antisocial by nature anyway so I get it. The part that really bothers me is that (and I admit I'm speculating a little bit) he feels he's messed up with my siblings and I and doesn't want to put the effort into fixing that relationship since he doesn't know where to start so he doesn't talk to us much or anything like that; but he buys presents for and makes plans to spend holidays with one of his friend's families rather than trying to make any effort to spend any time with us. It hurts me that he'd rather spend time with his "new" family than his own.
